What's New in Revit MEP 2014: Parameter Variance for Groups - Ability to have parameters vary for groups!

Revit MEP 2014 has some great enhancements, one of the most unique is the ability to have parameters vary by groups. One of the most common frustrations that clients have is the inability to schedule "groups" within Revit and we have suggested several different "workarounds" during support case issues at Ideate, Inc.

However with this minor enhancement it will open up more opportunities to push data into elements within groups and allow us to schedule this data. The reason for this, is we can use the “new variance parameter by group” functionality in 2014.

For example, when creating an instance project parameter (Text, Area, Volume, Currency, Mass Density, URL, Material, and <Family Type> only), you now have the option to allow the value to vary for different group instances. The user can edit the parameter value for an element in a group instance without changing the value for corresponding elements in other group instances.

Since you can vary the value of parameters assigned to groups, this will provide more flexible data reporting and increased support for COBie requirements. Data can also be incorporated into the operation and maintenance phase of a building lifecycle more efficiently.
